Re: Complete brain fade time - Vlan100 is up, line protocol is down

There are two things that will bring a vlan interface to the up/up state

1) having at least one physical port active in the vlan

2) having the vlan active on a trunk

Since this is a management interface it is likely that there would not be physical ports assigned to the vlan. So the issue is why is vlan 100 not active on the trunk. I wonder if the issue might be on the neighbor switch. What we see so far on this switch looks appropriate, so it would be appropriate to look on the neighbor switch.

Sorted !

Sh interface trunk was showing the correct vlan was assigned to the physical interfaces, so I removed it and re added it and it started working , this has happened twice for me and once for my colleague, same switch type and same operating system version - time for an upgrade methinks.
